| Sumario: | The lady beetle, <em>Menochilus sexmaculatus</em> is one of the biological control agents that can be used to control aphids. Presently, there is a lack of information about the effectiveness of this beetle to control aphids. The objective of this research was to study the functional response of<em> M. sexmaculatus</em> on <em>Aphis gossypii</em> at different ages of plants. All preys were exposed to one <em>M. sexmaculatus</em> adult for an hour at five different densities of aphids (10, 20, 30, 40, and 50 individuals) is four different ages of chilli plants (2,4,6, and 8 weeks). Data were analyzed by ANOVA and logistic regression to determine the type of functional response. The results showed that the ability of <em>M. sexmaculatus</em> to prey was not significant at 2 to 4 and 6 to 8 weeks old chilli plants. At 2 week old chilli plants <em>M. sexmaculatus</em> showed type I of functional response, while at 4, 6 and 8 weeks the functional response were type III. |
